For Problems $2$ and $3,$ consider a Brayton cycle with air as the working fluid with constant $$

$=1\mathrm{.}4$ and gas constant $=287\frac{J}{k}g.K,$ where $I_{\text{a}\text{m}\text{b}}=15C,P_{{?}_{?}}(amb)=\frac{1}{b}ar,$ pressure ratio of $25,$

and maximum cycle temperature, $I_{\text{m}\text{a}\text{x}}=1527C.$

P$02.$ Assuming ideal operation, Calculate the compressor exhaust temperature $($in $C).$

Question $3$

P$03.$ Calculate overall cycle efficiency for the Brayton cycle. Note that your answer should

be a number between $0$ and $1,$ not in $\%.$
